Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722700, here are decompositions:

79 + 8722621 = 8722700
97 + 8722603 = 8722700
223 + 8722477 = 8722700
229 + 8722471 = 8722700
241 + 8722459 = 8722700
271 + 8722429 = 8722700
277 + 8722423 = 8722700
307 + 8722393 = 8722700

Showing the first eight; more decompositions exist.
